Are Cariba Heine and Phoebe Tonkin Still Friends?

On-screen bond

Heine and Tonkin played best friends on H2O: Just Add Water – Rikki and Cleo – and their chemistry was a cornerstone of the show. The pair worked closely for four seasons from 2006 to 2010.

Off-screen relationship over the years

• Multiple sources confirm they have remained friends after H2O ended. Social media interactions and public events suggest the bond persists, though neither has given a detailed interview about it in recent years.
• In 2024, media speculation about Tonkin’s wedding to Paul Hooper raised the question of whether Heine attended – but no confirmed photographic evidence or official statement has emerged (People covers the baby news but not the wedding attendance).

The implication: Their friendship appears intact, but it’s kept private – consistent with Heine’s overall approach to guarding her personal life.

Does Cariba Heine Have Children?

Family details

• Yes, Cariba Heine has one son, born in May 2025 to her and husband Matt Pong (People). The child is her first.
• She shares limited information about her family. The baby’s name has not been publicly disclosed by any primary source.

Public statements about parenthood

• Heine announced her pregnancy on Instagram in December 2024 (Wikipedia). Daily Mail noted she was “besotted” in a headline about the baby arrival (Daily Mail).
• No further public comments about motherhood have been reported.

The deliberate privacy around her son aligns with the low-key lifestyle she has adopted since leaving major acting roles.

• IMDb lists recent works including a 2023 appearance in Everyone Is Doing Great and a 2021 credit for The Bureau of Magic (IMDb, the industry film database).

Life beyond the show

• Heine is active on Instagram, but her posts are largely personal – dance clips, family updates, and occasional throwbacks.
• She has not taken on a major acting role since H2O, but that doesn’t mean she’s left entertainment. Her mentorship work fills that creative space.
